Nice price, big bass

Alpine's Type-E subwoofers will fill up your ride with big bass without draining your bank account. These low-profile subs handle plenty of power, and still use the same tried-and-true design that's made this line so popular with budget-conscious bassheads. You'll get an amazing amount of rumble when you add one or two of these to your ride.

Built tough

The SWE-12S4 12" subwoofer handles up to 250 watts RMS. Alpine treats the pulp cone with Kevlar so it won't buckle or distort under heavy use, while the tough rubber HAMRS surround allows for maximum excursion while keeping the cone under control for more accurate bass. Extra venting maximizes air flow through your speaker, dissipating heat and increasing the sub's reliability. The heavy-gauge, stamped steel cage holds its shape through the most relentless pounding, so the bass stays tight.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

HAMRS: The woofer features a High Amplitude Multi Roll
Surround (HAMRS), made of Santoprene, that allows a large linear excursion and
greater SPL. The HAMRS design allows extreme excursions without sacrificing
valuable cone area.

Vented Pole Piece: The vented pole piece is flared at both
ends to maximize air flow from inside the motor structure. The Airflow Back Plate
combined with the Compound Radius Curve Extended Pole Geometry ensures that hot
air is not trapped inside the motor structure.

Spring Terminals: The spring post terminals are located on
one side of the woofer. The terminals will accept pin connectors, single banana
plugs, dual banana plugs (with standard 3/4" width), or bare wire up to 8
gauge.

Gasket Cover: Alpine uses a Concealed Mount Gasket System to
cover the mounting screws for a clean look. The black rubber gasket ring comes
already installed on the woofer and needs to be removed before installing the
mounting screws (not supplied). The gasket ring then snaps back into place once
the woofer is mounted.

Enclosure Compatibility

Sealed Box: Alpine recommends a sealed enclosure with an
internal volume between 0.69 and 1.04 cubic feet, with an ideal volume of 0.9
cubic feet. Sealed enclosures provide the most control over a woofer, will
handle a lot of power, and provide accurate sonic reproduction, making them
suitable to all types of music.

"Coolness Factor"

Build Quality

Ease of Use

Sound Quality

Value

I had just bought these subs yesterday with a slot ported box and hooked them up with a crunch 1500 watt amp and man do these things pound for the price, alpine is and always will be a great product. I still have yet to play with my amp settings (they are set low as i am breaking it in still) and they hit hardd would highly recommend to anyone looking for a good system.

Pros:Great sound quality and overall great build, i do not think i will be undersatisfied with these and would recomend to many

Unbeatable for the price

Very surprised how good this sub sounded for the price. The only reason I bought it was so I would have some bass while my JL Audio W3 got repaired. But after hooking it up I wondered if there was really a need for the W3. It was supposed to be a scratch n dent but mine came in mint condition.

all I can say is wow

man, I bought these subs for a temporary fill while I waited for the new JL Audio thin subwoofers to come out and man, there is no reason to replace them, the bass is so tight and it pounds, best of all these were open box and I got both for less than $100.. to my door. I see no reason to buy the JL's now.

very nice

Picked this sub from Crutchfield scratch and dent. Looks perfect. Nice clean, hard hitting base. Plays upper base very nice so it has a very good sound quality. Very sturdy construction that looks really cool. Running with a sound ordinance 4 channel amp with bridged mono sub at 240 watts. More than enough power and sound to fill my car and any car next to me.

Very Good Sound

Very well built, easy to install. Got this hooked up to a older Sony Xplod Amp and that is being fed from a Pioneer AVH P4400 Head Unit. The sound is great for the music I listen to and I can really tweak everything and make it how I like it.

Get it now

If you are looked for an entry level sub woofer just to get your system bumping, this is the one to get. I only have one in a ported box in an SUV, and it will absolutely pound!

It will take some abuse also. I originally had it underpowered, and now I am overpowering it, but it is taking it like a champ. I am currently running 380 watts rms to it, and it is doing just fine. Of course, I am careful with it and have the amp adjusted accordingly (as much as is possible when overpowering by this much power).

That's all I really need to say. Another great Alpine product. Just get it.

Alpine SWE-12S4

This budget friendly sub is tops for what you pay hands down. The lows come easy and power handling is superb for an entry level product. The sound quality is great. Not only does it play low & loud in a sealed setup but it hits the upper bass just as well! Not many 12's can lay claim to that in this price range. I can't imagine what alpine's higher end product would do to my ears! This is the best product out their for the price! Awesome value.

Pros:Lightweight, yet still a performer. Hits the upper bass just as well.

Cruthfield still #1

Alpine goes without saying. I ordered a sub box from ebay. Mistake. i ordered the sub from Crutchfield. I ordered the box 4 days before the sub. the sub from Cructhfield arrived 3 days before the box. i should have used Crutchfiled for the whole set up. Flawless transaction great products.

Great sub for the $$

I have been a big Alpine fan for many years, and I needed some bass for my Durango. I picked this one because I have been a big fan of Alpine sound, and this sub is exactly what I expected. I have it in a sealed box 1.0 cu size, and I am pushing it with channels 3/4 bridged at 225 watts, and it fills my suv with great deep base. In this price range I feel it is one of the best options!

Pros:Alpine name behind it, and it looks like it is built well. The bass is incredible for a single woofer running off a 4 channel amp.

Alpine SWE-12S4

Great sub for the price, picked it up on the outlet for $50. Cannot match it for sound to price ratio. Replaced an aging clarion sub in my wifes 350z. Hits alot harder than the old sub and looks better also. Powering it with a Sound Ordinance sub amp and they pair great. Good sound for the price.

The missing link!

This sub sounds great! I am pushing it with a Boston amp bridged for 160 watts and it fills my Silverado with nice tight deep base. I replaced the stock head unit with a Kenwwood HD receiver but was not happy with the base response from the stock speakers. After getting this sub and building the recommended size sealed box, WOW, what a difference. It is what was missing from the total sound of the stereo. I am more than pleased with the end result. Buy this sub and give it enough power and you won't be disappointed!

Bang for your buck!

Let me first say that i am not a pro woofer guy. i had a pair of kicker comp 12s in a sealed truck box for my 07 ranger with a cruch amp and yeah it was alright. i only got it because it was cheap from craigslist. i knew being how i am, i always like new stuff from high quality makers, that i would upgrade. little did i know if would be a week after my kicker set up :P i bought 2 of these with an alpine mrp 500 amp and a SO dual ported box. let me start by saying they build quality was exelent! the motors are way more girthy in person than in the picture. the basket was thick and strong and i really like the air port behind the motor. the only reason i took one star off of build quality was becase i felt the metal where the screw mounts were was a little week, but its not going anywere for sure. when i first hooked them up i was blown away by their sound and their SPL capabilities! holy crap! that mrp 500 powers these bad boys no problem. they arnt broken in yet so i havnt ben blasting music through em but when i do its only for a few seconds to see what they can do. One other thing i noticed was the rubber ring that covers the screw holes comes off easily and is kind of a pain to get back on but its really not that big of a deal just kind of an inconvenience when your putting something in there and it accidentally snags it. over all i would say i love this system way better than my kickers and if you want affordable bass that will impress anyone... definately go with alpine

Amazing sound quality, huge bass for little money

This was my first Subwoofer, and after hearing other subs, I was completely amazed at how clear the music is, considering how loud the bass is. After tuning it and breaking it in, you won't get a better sound quality for the price. It's truly a subwoofer to be proud of! I highly recommend this as a starter or mid entry level subwoofer.

Pros:Durability, sound CLARITY, nice range of bass, looks good.

Cons:the bass evens out at higher volumes, but still beats extremely hard.

Alpine Rules for Price vs What you get in Return

I have used Alpine Subs (Most of them 12") EXCLUSIVELY since I used to work as an Authorized Alpine Installer 30 Years ago. It never ceases to amaze me the quality and "Grin Factor" you get for such a reasonable price with Alpine Products. I am running these in Parallel from the 5th Channel of an Alpine 5 Channel Amp (300 Watts). Again, my system sounds awesome. I also used the previous model of these (Still E-Type) in my son's pickup with the same amp and they pound there as well. I have yet to blow any Alpine sub up. They sound incredibly warm and real (Probably due to the pulp cones) and the new surrounds on them make for great excursion. Mind you, I have never overpowered any of this series of sub and as long as you keep them in the 300 +/- Watt RMS zone you will be grinning for years! Add to that the killer price you get from Crutchfield and I really can't see you going wrong. If you are on the fence with these, put them in with the idea that you will "Upgrade" at a later time and I think you will find that you will have them forever.

great subs!

i didnt know what to expect when i ordered these because no one had written a review on them,but i got them today and wow they are a huge upgrade from the two old memphis's i had in there before and there not even broke in yet
